Final-year dissertation: the complete step-by-step guide

A dissertation is rarely written in one go: it is built step by step, from choosing a topic to the final defense. This guide brings all the steps together in order, each with a link to a detailed article. It is written for bachelor's and master's students, engineering and business school students and nursing students, in Morocco and across the French-speaking world.

In short: a dissertation is a personal research project that answers a precise question with a rigorous method. It almost always follows the same path: choose a topic, write the research problem, review the literature, define the methodology, collect and analyze data, discuss the results, then defend the work in front of a jury.

What is a final-year dissertation?

The dissertation is the document that closes a degree. It shows that you can ask a research question, find out what has already been written, collect reliable information and draw well-argued conclusions. Depending on the program it is called a dissertation, a thesis, a final-year project report (PFE) or a professional thesis.

• Bachelor's dissertation: often 30 to 60 pages, a simple question, a survey or a case study.

• Master's dissertation: usually 60 to 100 pages, a stronger literature review and a more advanced data analysis.

• Final-year project report: linked to an internship or a company project, with a diagnosis and a solution. See our final-year project report example.

These ranges vary between institutions: the rule that counts is always your program's official guide.

Step 1: choose a feasible topic

A good topic interests you, fits your program and can be handled with your resources and deadline. Before committing, check that you can access the field (company, hospital, school) and sources. Our 6-step method: how to choose a dissertation or final-year project topic.

Step 2: write the research problem

The research problem starts from an observation, shows what studies say, identifies a gap and leads to a clear research question. It is the part supervisors criticize most often. Full method and example: how to write a research problem statement.

Step 3: review the literature

The literature review presents and compares existing work on your topic. It justifies your research problem and provides the concepts and measurement scales you will need. Read how to write a literature review and apply APA 7 style for your citations from day one.

Step 4: build the outline

The most common structure for a research dissertation is:

1. General introduction

2. Theoretical framework (literature review, concepts, research model)

3. Methodology (study type, population, sample, data collection tool)

4. Results

5. Discussion

6. General conclusion, limitations and recommendations

7. References and appendices

Nursing institutes use a variant: see the ISPITS nursing thesis structure. For a company project, the report adds a presentation of the host organization and a diagnosis.

Step 5: define the methodology

The methodology explains how you will answer the question: a quantitative approach (questionnaire, figures), a qualitative one (interviews, observation) or a mixed one. You describe the population, the size and selection of the sample, the data collection tool and the planned tests.

• For a questionnaire: 8 rules to design a dissertation questionnaire.

• For the number of respondents: sample size formula and examples.

Step 6: collect and analyze the data

Once the data is collected, it must be cleaned, coded and analyzed with suitable software: Excel for simple descriptive statistics, SPSS for statistical tests, SmartPLS for structural equation models. The analyses most often requested in dissertations are:

• scale reliability with Cronbach's alpha in SPSS;

• the link between two categorical variables with the chi-square test;

• the effect of several variables on another with linear regression in SPSS;

• models with latent variables with SmartPLS and PLS-SEM.

Step 7: write the results and the discussion

The results describe what you found, without interpretation: tables, charts, test values. The discussion then compares these results with the studies cited in your literature review: do they confirm, nuance or contradict what was known? The discussion is where the jury judges your analytical ability.

Step 8: introduction, conclusion and front matter

The introduction and conclusion are written (or finalized) last, once everything else is stable. Method and examples: writing the introduction and conclusion. Do not forget the front matter: title page, acknowledgements and dedication, table of contents, list of abbreviations.

Step 9: prepare the defense

The defense usually lasts 15 to 20 minutes of presentation followed by the jury's questions. Three articles to prepare it:

• prepare your thesis defense in 7 days;

• build a strong PowerPoint defense presentation;

• the jury's most common questions and how to answer them.

What timeline should you plan?

For a dissertation prepared over one semester (about 4 to 5 months), a realistic plan looks like this:

• Month 1: topic, research problem, first readings.

• Month 2: literature review and methodology, building the data collection tool.

• Month 3: data collection (questionnaire, interviews, company data).

• Month 4: analysis, results and discussion.

• Month 5: introduction, conclusion, proofreading, formatting and defense preparation.

Always keep a two-week margin: supervisor feedback and data collection almost always take longer than planned.

The mistakes that cost the most points

• A topic that is too broad to handle in a few months.

• A research problem without a clear research question.

• Sources not cited or cited incorrectly (plagiarism risk).

• A questionnaire built without a link to the objectives.

• Results presented without interpretation or discussion.

• Careless formatting and rushed proofreading.

Frequently asked questions

How many pages should a dissertation have?

It depends on the level and the institution: often 30 to 60 pages for a bachelor's degree and 60 to 100 pages for a master's degree, excluding appendices. Your program's guide is the reference.

What is the difference between a dissertation and a final-year project?

A dissertation is built around a research question. A final-year project usually starts from an internship or a concrete company project and proposes a solution. Both require the same methodological rigor.

Is a statistical analysis mandatory?

No. A qualitative study (interviews, content analysis) is just as valid. However, if you use a questionnaire, the jury expects appropriate and correctly interpreted statistics.

Which software should I use to analyze my data?

Excel is enough for descriptive statistics. SPSS is the most widely used for tests (chi-square, t-test, ANOVA, regression). SmartPLS suits models with several latent variables.

Can I get support for my dissertation?

Yes. Methodological support (research problem, methodology, data analysis, proofreading) is allowed as long as the work remains yours: you must understand and be able to defend every part in front of the jury.
